Clearing out the cache might be necessary to unlock it by kicking, but I have managed to unlock it having the update and not kicking but simply by stringing LT,RT,LT combos. It was kind of weird because the achievement popped up when I managed to pull off third combo (according to my calculations), however this was the third time I was playing episode 2 SO MAYBE the game remembers correctly performed combos from all playthroughs. Bottom line: I didn't need to get rid of the update to get this achievement.
